These exercise are good, and im sure everyone taking part will do really well. But put them in real combat, and some of them (the ones who aced all their medical exams) will crack, because real bullet and shrapnel wounds look nothing remotely like any of the “wounds” shown here.

An interesting exercise, however, I see no use of helicopters. Even an old broken down helicopter is useful for practicing loading and unloading patients.
With the range of modern weapons, a medical facility has to be so far from the fighting that only helicopters can be used to evacuate patients.
